Plant growth chambers from the APT.line™
KBW series:
Plant growth chambers with optimal lighting conditions
Precision combined with maximum dynamics. KBW exceeds any requirements with respect to optimal lighting and temperature conditions for exactly defined culture processes. Extremely short reaction times keep all growth parameters in equilibrium -- natural simulation as never before. Handling is truly enhanced by the integrated real-time clock function in the controller.
- Electronically controlled APT.line™ preheating chamber technology
- Temperature range: -10 °C to 60 °C (14 °F to 140 °F) without illumination
- MP controller with 2 programs with 10 sections each, alternatively switchable to 1 program with 20 sections for programming day/night cycles
- The time interval of single program sections can be adjusted up to a maximum of either 99:59 hours or 999:59 hours. This adjustment applies to all program sections.
- Integrated week program timer with real time function
- Time functions: delayed ON, delayed OFF, and temperature-dependent delayed OFF

3) Mean values based on 9 measuring points. The distance between the measuring plain and each illuminated shelf is 12 cm (4.7 inch).
* Light measurement using Quantum sensors with cosinus correction positioned vertically upside.
** KBW 720 / 115 V: Standard equipped with 2 illumination cassettes and 2 shelves stainless steel.
All specified technical data apply for standard equipment operating at an ambient temperature of + 20 °C (68 °F), with line voltage fluctuations of ± 10%. These typical average values for series equipment were determined in accordance with the BINDER factory standard. They are based upon the recommended distances from the inner chamber walls, namely 10% of height, width and depth. Differing ambient temperatures or variances in the design of individual equipment may produce different performance data.
We therefore recommend that equipment be calibrated and/or validated on a case-by-case basis when working at the extremes of the permissible ambient temperature range.
